Building for the versatile/realview platform makes it possible to select any of ARM926 and the v6/v6k/v7 CPUs, as well as ARM7TDMI in the same kernel config, so I assumed that this was actually a valid configuration aside from bugs. Would an attempt to make a combined v5/v6 kernel result in unacceptably bad code, or is this just too much work for anyone to be bothered with and little practical value?
